← ScienceWhat effect does increasing the activation energy have on reaction rate in chemical kinetics?
A)Decrease reaction rate exponentially✓
B)Increase maximum reaction rate linearly
C)No effect if temperature increases
D)Increase equilibrium constant immediately
💡 Explanation
When activation energy increases the collision frequency decreases because fewer molecules possess sufficient energy to overcome the barrier, reducing the speed by an exponential dependence based on the Arrhenius equation. Therefore decreased reaction rate results, instead of increased rate, eliminated effect, or immediate equilibrium constant change which need catalyst availability or mass change.
